Fatty Acids

A lipid is an organic compound such as fat or oil. Organisms use lipids to store energy, but lipids have other important roles as well. Lipids consist of repeating units called fatty acids. Fatty acids are organic compounds that have the general formula CH3(CH2)nCOOH" role="presentation" style="display: inline-table; font-style: normal; font-weight: normal; line-height: normal; font-size: 17.6px; text-indent: 0px; text-align: left; text-transform: none; letter-spacing: normal; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; padding: 0px; margin: 0px; position: relative;">CH3(CH2)nCOOHCH3(CH2)nCOOH, where n" role="presentation" style="display: inline-table; font-style: normal; font-weight: normal; line-height: normal; font-size: 17.6px; text-indent: 0px; text-align: left; text-transform: none; letter-spacing: normal; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; padding: 0px; margin: 0px; position: relative;">nn usually ranges from 2 to 28 and is always an even number. There are two types of fatty acids: saturated fatty acids and unsaturated fatty acids.

Saturated Fatty Acids

In saturated fatty acids, carbon atoms are bonded to as many hydrogen atoms as possible. This causes the molecules to form straight chains, as shown in the figure below. The straight chains can be packed together very tightly, allowing them to store energy in a compact form. This explains why saturated fatty acids are solids at room temperature. Animals use saturated fatty acids to store energy.

Unsaturated Fatty Acids

In unsaturated fatty acids, some carbon atoms are not bonded to as many hydrogen atoms as possible due to the presence of one or more double bonds in the carbon chain. Instead, they are bonded to other groups of atoms. Wherever carbon binds with these other groups of atoms, it causes chains to bend (see figure above). The bent chains cannot be packed together very tightly, so unsaturated fatty acids are liquids at room temperature. Plants use unsaturated fatty acids to store energy.

Figure 14.2.2" role="presentation" style="display: inline-table; font-style: normal; font-weight: normal; line-height: normal; font-size: 16px; text-indent: 0px; text-align: left; text-transform: none; letter-spacing: normal; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; padding: 0px; margin: 0px; position: relative;">14.2.214.2.2: Saturated fatty acids have only single bonds while monounsaturated fats have one double bond and polyunsaturated fats have more than one double bond.

Lipids and Diet

Unsaturated fat is generally considered to be healthier because it contains fewer calories than an equivalent amount of saturated fat. Additionally, high consumption of saturated fats is linked to an increased risk of cardiovascular disease. Some examples of foods with high concentrations of saturated fats include butter, cheese, lard, and some fatty meats. Foods with higher concentrations of unsaturated fats include nuts, avocado, and vegetable oils such as canola oil and olive oil.

Fructose is a simple carbohydrate sugar, while triglycerides are the lipids or the fats of the body. Thus, option C is accurate.

Triglycerides are lipids of the body that are formed of fatty acids and glycerols. It makes the body fat of the animals and of the plants. They are stored in cells for future use and provide energy when needed.

Fructose is a monomer that is the simplest carbohydrate sugar and is generally found in sugarcane, honey, watermelon, grapes, apples, etc.

Therefore, option C. fructose is sugar and triglyceride is fat is correct.

it shows covalent bonds

The type of bond the diagram shows is covalent bond. As shown the sharing of electrons in the diagram.

Bonds are defined as any of the interactions that lead to atoms joining together to form molecules, ions, crystals, and other stable species that make up the familiar materials found in everyday life. The ability to build molecules is made possible by a chemical bond, which is a strong attraction between atoms, ions, or molecules. Chemical bonds that hold molecules together also form temporary connections vital for life.

Covalent bond are defined as a type of chemical link where atoms share electrons to create electron pairs. Low melting and boiling temperatures, low vaporization heat, low water solubility, and poor conductivity are four characteristics of covalent compounds.

Thus, the type of bond the diagram shows is covalent bond. As shown the sharing of electrons in the diagram.

Answer:

barium sulfate is insoluble (unable to dissolve) in water.

the general equation for the reaction between solid barium sulfate and nacl solution is this:

BaSO4 (s) + 2NaCl (aq) --> BaCl (aq) + Na2SO4 (aq)

to sum this up, to compare the solubility,

1. barium sulfate cant dissolve in pure water.

2. barium sulfate dissolves in nacl solution to give aqueous (aq) barium chloride (bacl) and aqueous sodium sulfate (na2so4), as shown in the equation above.

good luck!

The solubility of barium sulfate in pure water to zero as compare to the solubility in NaCl solution.

Solubility is a property of any substance that defines how easily can be any substance will get dissolved or show dissolution.

         BaSO₄ (s) + 2NaCl (aq) → BaCl (aq) + Na₂SO₄ (aq)

The reaction, Fe2O3 + 3CO------> 2Fe + 3CO2 is an oxidation-reduction reaction.

An oxidation-reduction reaction is a reaction in which there is a change in oxidation number from left to right in the reaction. This is because, a specie is oxidized and another specie is reduced.

In the reaction;  Fe2O3 + 3CO------> 2Fe + 3CO2, we can see that the oxidation number of iron decreased from +3 on the left hand side to zero on the right hand side. The oxidation number of carbon was increased from + 2 to +4.

Answer:

Looking at the table, Silver is definitely the most conductible metal there. It has the lowest electrical resistivity which means it allows for an easier flow of electrons, and it also has a higher thermal conductivity which means it would exhibit a higher conductivity. Diamond has the highest thermal conductivity, but the electrical resistivity is extremely high and due to its giant covalent/tetrahedral molecular structure (being an allotrope of Carbon), electrons can't necessarily jump around. Diamond wouldn't be a conductor at all.

The most simplest composition and structures provide a higher thermal conductivity. For example, with Diamond, we know that it is a structure made of covalent bonds of carbon, so its thermal conductivity is high.

Q1

Copper

The mass of water, H₂O produced from the reaction is 72.06 g

We'll begin by calculating the mass of NH₄NO₃ that reacted and the mass of H₂O produced from the balanced equation.

NH₄NO₃ —> N₂O + 2H₂O

Molar mass of NH₄NO₃ = 80.03 g/mol

Mass of NH₄NO₃ from the balanced equation = 1 × 80.03 = 80.03 g

Molar mass of H₂O = 18.01 g/mol

Mass of H₂O from the balanced equation = 2 × 18.01 = 36.02 g

From the balanced equation above,

80.03 g of NH₄NO₃ reacted to produce 36.02 g of H₂O

Finally, we shall determine the mass of H₂O produced by the reaction of 160.1 g of NH₄NO₃.

From the balanced equation above,

80.03 g of NH₄NO₃ reacted to produce 36.02 g of H₂O.

Therefore,

160.1 g of NH₄NO₃ will react to produce = (160.1 × 36.02) / 80.03 = 72.06 g of H₂O.

Thus, the mass of water, H₂O produced from the reaction is 72.06 g

The shielding effect of bromine is greater than chlorine because there are more filled orbitals than in chlorine.

This is the process where by electrons are protected by the pull attraction of the nucleus with the use of electron shells. The shielding effect increases down the group of the periodic table and increases across the period. This is because when you move down the group, there's an increase in the number of shell by 1 and it helps to reduce the effect of nuclear attraction on the electrons. However when you move across the period, there's an increase in the numbers of electron with the same shielding electrons from group 1(a) across the period to group 7(a).

Shielding effect is primarily dependent on the numbers of electrons in the inner shells as well as the type orbitals.
